Plus, if we had higher traditional fight stats, we may have been thrown into the meat grinder during wartime, but instead our sealing and 7th path stuff and leadership were more worth the trade off. Resolve is one of those stats that's useful, but not obvious in the same ways, so it's good for us to build up without getting attention. I think that's why both Akane and Kei had plans to build up defensive skills before offensive, so they wouldn't get killed off for being glass cannons.
Instead, with SC at 40 we could do a bunch of research we couldn't have gotten through otherwise. If a lot of our utility comes from sealing, then FOOM giving us more ability to do sealing has to be weighed accordingly. We're getting through twice as many projects because of it, and given some of those projects are "+20% to stat seals" and "defend leaf from aerial bombardment", that matters.
Plus, and I don't think I've seen this listed before, FOOM gave us the major advantage of "be able to dump huge amount of XP into a specific thing when we need it", by basically being an XP sink early on, when nothing was super pressing, to give payoff later. So when we realized we needed to put a bunch of XP into earth shaping, or discovered the paradigm of PS, etc, we could put XP into those at a faster rate than normal. Same with the good techniques from Oro that we didn't have access to until recently. Even leaving aside what FOOM does for Snowflake, or for multitasking, or making sure we always have seals and lootboxes and research on the go, it allows us to Pivot to new shiny, in a way that shapes the EN. At least, that's always been part of my take on it. Past prep, for current growth OR flexibility.
